1. The Version is RHEV-M 3.3 & Cloud-init is
cloud-init-0.6.3-0.12.bzr532.el6.noarch
2. In Webadmin, i don't find any option to set Cloud-init data's. I checked
under New VM->Initial Run.. Am i looking at the right place?
How to enable cloud-init support in engine?
I have installed cloud-init package in RHEV-M & also in Template.
Please suggest.
